Cannot see warnings in interactive mode
Using ion-shell 1:1.0.0-alpha4.1 from PPA on Ubuntu 19.04, doing
let res=@(ls)
echo @res[0]
produces no warning, whereas such output is expected (see #901 (closed)):
ion: expansion error: can't expand a scalar value 'res' as an array-like
Is there anything I can do to help investigate ?
